Buffs/Stances could stack on use?

This would be a buff in some ways and a nerf in others.

Thinking of it like this:

- Buffs/Stances cannot be stacked in your deck
- The single glyph is not available in your deck while the buff/stance persists
- Using another of the same glyph will stack and refresh your buff/stance

For example:
1. You have 4 Berserk Stance glyphs in your deck
2. You use one, gaining the Berserk Stance.
3. You have 3 remaining Berserk Stance glyphs in your deck
4. You use another, your Berserk Stance refreshes and gains a stack (2 stacks).
5. You have 2 remaining Berserk Stance glyphs in your deck
6. Your buff expires.
7. You have 4 Berserk Stance glyphs in your deck

This would mean the glyph would be removed from your deck while active. This would also allow some buffs to be tweaked around the idea that you can only spread 5 stacks around at any one time.

Just a thought. Would make buffing something you do in combat and also something that is more limited. By the same note, buffing could become more powerful to match the time it would take to use a damage spell instead.

It would also mean a more supportive player could be persistently useful in a fight simply as a buffer as well as a healer. Also, buffs could then gain extra effects when stacked.

e.g. Like a buff that adds flat damage to auto attacks per stack, but each new stack also heals the target for a percentage the extra damage dealt since the last stack was added. This would mean you would want to slowly build it up for bigger heals, finally resulting in the 5th stack which simply deals a greater amount of flat damage and "locks out" the heal for a while until it expires.
